Sierra Snowpack Could Drop Significantly By End of Century

A future warmer world will almost certainly feature a decline in fresh water from the Sierra Nevada mountain snowpack. Now a new study by Lawrence Berkeley National Laboratory that analyzed the headwater regions of California’s 10 major reservoirs, representing nearly half of the state’s surface storage, found they could see on average a 79 percent drop in peak snowpack water volume by 2100.

How Drought and Other Extremes Impact Water Pollution

One in 10 Americans depends on the Colorado River for bathing and drinking. Last fall’s record-high temperatures reduced Colorado snowpack in winter 2018 to 66 percent of normal, sparking concern over water shortages downstream and leaving water managers fearful of a repeat. Berkeley Lab hydrological science expert Bhavna Arora explains how unseasonably warm weather and drought can affect water quality.

Algorithm Provides Early Warning System for Tracking Groundwater Contamination

Groundwater contamination is increasingly recognized as a widespread environmental problem. The most important course of action often involves long-term monitoring. But what is the most cost-effective way to monitor when the contaminant plumes are large, complex, and long-term, or an unexpected event such as a storm could cause sudden changes in contaminant levels that may be missed by periodic sampling?

Scientists Dig Deep to Track Down California’s Ever-Changing Groundwater Supply

Erica Woodburn, a research scientist in Berkeley Lab’s Earth and Environmental Sciences Area, is developing a new modeling technique that employs remote sensing technology to understand the effects of climate change on California’s groundwater supply.

Erica Woodburn first fell in love with hydrogeology as an undergraduate majoring in geology. Today, she is a research scientist in the Lab’s Earth and Environmental Sciences Area.

Understanding Effects of Climate Change on California Watersheds

California relies on the Sierra Nevada snowpack for a significant portion of its water needs, yet scientists understand very little about how future changes in snowpack volume and timing will influence surface water and groundwater. Now researchers at Lawrence Berkeley National Laboratory are developing an advanced hydrologic model to study how climate change might affect California watersheds.

Berkeley Lab Aims for Big Breakthroughs in Water Technology

Berkeley Lab is launching a new research institute to focus resources on its growing portfolio of projects for water innovation – from nano-engineered desalination solutions to ultra-high resolution climate modeling for watershed predictions to novel groundwater management approaches.

Diamonds From the Deep: Study Suggests Water May Exist in Earth’s Lower Mantle

A new study, which included experiments at Berkeley Lab, suggests that water may be more common than expected at extreme depths approaching 400 miles and possibly beyond – within Earth’s lower mantle. The study explored microscopic pockets of a trapped form of crystallized water molecules in a sampling of diamonds.

Research Becomes Reality in Study of Fire Impact on Sonoma Water Resources

Catastrophic fires in Northern California burned more than 110,000 acres in Sonoma and Napa counties last month – including 8 percent of the Russian River watershed. Now with the rainy season underway Berkeley Lab’s research – which seeks to understand how the hydrology and microbiology of the surface and groundwater system respond to extreme events – has become even more critical.

Cool Roofs Have Water Saving Benefits Too

The energy and climate benefits of cool roofs have been well established: By reflecting rather than absorbing the sun’s energy, light-colored roofs keep buildings, cities, and even the entire planet cooler. Now a new study by Berkeley Lab has found that cool roofs can also save water by reducing how much is needed for urban irrigation.

Berkeley Lab Names Peter Fiske Director of Water-Energy Resilience Institute

Berkeley Lab has tapped Peter Fiske to be the director of its Water-Energy Resilience Institute, a new position that underscores the Lab’s commitment to developing solutions for the challenges associated with the interdependence of water and energy systems. Fiske will join Berkeley Lab on May 15.
